CIMR-AU2A0040FAA Yaskawa

10 HP , Serial A1000

The A1000 is a full featured drive, providing outstanding quality, performance, flexibility, and environmental friendliness through 1000HP. Enjoy network communications, feedback, and expandable I/O to control anything from simple fans and pumps to complex machines. For new installations or retrofits, the A1000 provides a single robust solution, regardless of your application.

Error codes

CPF11 to CPF14 and CPF16 to CPF19

Fault name : Control Circuit Error.

Cause1 : There is a self-diagnostic error in the control circuit.

Possible solution : Cycle power to the drive

If the problem continues, replace the control board or the entire drive. Contact a DMEB Service technician for help.

Cause2 : Connector on the operator is damaged.

Possible solution : Replace the operator

FAn

Fault name : Internal Fan Fault

Fan or magnetic contactor failure (detected when L8-32=0 to 2)

Cause1 : Internal cooling fan has malfunctioned

Possible solution : Cycle power to the drive

Check for fan operation.

Verify the cumulative operation time of the fan with monitor U4-03, and verify the cumulative operation time of the fan maintenance timer with U4-04.

If the cooler fan has exceeded its performance life or is damaged in any other way, replace the fan.

Cause2: Fault detected in the internal cooling fan or magnetic contactor to the power supply.

Possible solution : Cycle power to the drive

If the fault continues to occur, replace the power board/gate drive board or the entire drive.

Please, contact a DMEB Service technician.

GF

Fault name : Ground Fault

A current short to ground exceeded 50% of rated current on the output side of the drive.

Setting L8-09 to 1 enabled ground fault detection.

Cause1 : Motor insulation is damaged.

Possible solution : Check the insulation resistance of the motor.

Replace the motor

Cause2 : A damaged motor cable is creating a short circuit.

Possible solution : Check the motor cable.

Remove the short citcuit and reapply power to the drive.

Check the resistance between the cable and the ground terminal.

Replace the cable.

Cause3 : Excessive leakage current at the drive output.

Possible solution : Reduce the carrier frequency.

Reduce the amount of stray capacitance.

Cause4 : The drive performed a current offset adjustment while the motor was rotating.

Possible solution : The set value exceeds the allowable setting range while the drive automatically adjusts the current offset. This generally only happens when attempting to restart a PM motor that is coasting to stop.

Set b3-01 to 1 to enable Speed Search at Start.

Perform Speed Search 1 or 2 (H1- =61 or 62) via one of the external terminals.

Note : Speed Searches 1 and 2 are the same when using OLV-PM.

Cause5 : Hardware problem

Possible solution : If the problem continues, replace the control board or the entire drive. Contact us for more informations.
